Abstract
The invention relates to a method for producing three-dimensional objects, comprising producing a three-dimensional structure by sequential selective curing of layers of a composition curable with visible and/or ultraviolet light into a solid polymeric material by sequential exposure of the individual layers to UV and/or visible light, whereafter a three-dimensional object is produced by use of the three-dimensional structure thus formed, followed by removing the three-dimensional structure from or of the three-dimensional object, characterized in that removing the three-dimensional structure is accomplished by chemically cleaving the polymeric material as well as simultaneously or subsequently dissolving the material in a solvent or mixed solvent and/or melting the material.
